A single-engine plane crashed Tuesday morning at an airport on one of the Tsushima Islands in Nagasaki Prefecture, killing all three people aboard, authorities said.

Despite being pulled from the Sokata TB-21 and being rushed to a hospital, the three people were pronounced dead, according to the Land, Infrastructure and Transport Ministry.

Ministry officials identified them as 59-year-old Kazuhiko Miyake, a staff member at Sojo University in Kumamoto City; 43-year-old aircraft mechanic Hideo Muto; and company president Keiyu Ueno, 54. The officials said the flight plan listed Ueno as the pilot and the flight itself as a training session.

According to the officials, as the plane was preparing to land at the airport, it crashed on a slope just before the runway at 10:53 a.m.
